INSULATED REGEP'IACLE.

. v sp m or e Patent. Patented some 13, roll, Application filed Jun'c15, 1908. Serial No. 438,471.

To all whom it may concern: 1 Be it known that'l, HERMAN Snow, a citizenof the United States, residin at Chicago, in the county of Cook andbtate of Illinois, have invented new and useful Improvements inInsulated Receptacles, of

"which the following is afull, clear, and ex act description Thisinvention relates to improvements in insulated receptacles, the objectbeing to provide a simple and practical device for maintaining a highor' low temperature within the receptacle, for a limited period of time.

Another object is to provide a removable cover having a closed tank orcompare,

v ment for containing a body of Water or other substance which "may beeither frozen by suitable freezing a paratns, or heated to a very highdegree 0 temperature, for nxaintaining a low orhigh degree oftemperature 1 in the receptacle,dependingnpon the use grangement, a"description of which will ,be :foundin the .iollowing s eeification andthe towhich the'receptacle is to be put.

To snchend this invention consists in oer-V .tain novel features ofconstruction and aressential features" of W ich Willbe more definitelypointed out I in the appended claims l Q: The inventionis clearly,illustrated in the drawings furnished herewith in which- Figure 1 is acentral, vertical section-of 'an apparatus containing myimpl-oven'cents.-

Fig. 2 is an under-plan vicw'of the inn proved cover.

- In these views 1, is a-receptacle having an innerchalnber 2 forreceiving the commodities and 3 is an insulating chamber sure roundingthe inner chamber and inwhlch 1s placed o heat nonconducting substances,Wsnohas cork, magnesia, asbestos, or the hke.

" Any wellknovvn heat non-conducting Substance may be, placed Withinthis chaniher.

The inner chamber 2,-is formed hy'a wall 5, closed at the lower end by abottom 6, and

7 thischamber is open atthe top, the opening b'eingsnrrouncled by anoutwardly flaring neck piece 7. The lower edge of the neck iece 7, isflanged outwardly as seen at g the side Wall 5, is soldered to the edgeof said flanged portion 8, as at 9 and to the neck piece at 10. Theupper edge of the neck piece 7, is extended out 1n the form of a,horizontal flange 11, which is connected to the outer orsurroundingfipvall 12, of the receptacle by means of a joint 13. Theouter wall is closed along its lower edge by ni'hottom 14;.

My improved-cover is seen at 15, and as shown, has a fiarin side Wall16, adapted to' fit snugly ithin'tie tapering neck piece 7, of thereceptacle and to extend down somewhat below the flange 8. 1A bottonrll,is formed upon the lower edgeof the side wall 1d, and the upper edge ofsaid Well isilanged outwardly atl8, to receive a top piece 19,

which is secured to the fiange 18, as by a seam joint 20. of water orother freesoble substance 21, over which is pieced o corlr'pnrtition'17, of the cover are preferably covered with some Water proofingsubstance, and the cork partition 1s forced down 'ov'er'the Water tomake a perfectly tightf oint "with the covon After the cork 22, has beenpnt in place the space above the cork is filled with a heat vnon-conducting substance such as, cork, Inagnesm, asbestos or the like,after which the top" 19, issecnred' in place upon the flange 18.

When the deviceis to he need for mainmining a low degree of temperaturein the receptacle, the cover 15, is placed in some sniteolerefrigerating: apparatus and the Water therein frozen into a sake ofice. The

receptacle itself may also be cooled oil and then filled with the foodor liquid which it is desired to preserve in o cool condition. The cover15, is then forced down into the The cover contains a body The innerface of the Wall 16, and bottom neok of thefredeptacle,.-thns closing,the in ner' chamber and completely snrroundingit with a jacket of heatnon-condnctin z snbstance. This heat non-conducting jacket itself willeffectually prevent the outer fltlI108- phere for a limited period oftime, from substantially increasing the temperature within thereceptacle, but with the assistance of the lee pack in the cover, thelow temperature within the receptacle will be maintained for a muchlonger period. a a The advantage of having an insulated Ice tank in thecover is readily apparent. To

prepare the cover for use, it is simply placed in the; refrigeratingplant end the water within the tank frozensolld. v If it is desired tomaintain a high degree of heat in the receptacle, the cover can beplaced upon a stove and the Water in the tank heated up to a very highdegree of temperature, after which the cover he placed in the neck ofthe receptacle, thereby .niaintainingthc heat within the receptacle amuch longer period of time. It should be noted that a slightspace isleft between the lower edge of the cover 15,

and the wall 5, of the inner chamber, thus forming an annular groove atthis point. This construction provides a sort of deflecting chamber sothat the rising air in the receptacle will be turned down into thereceptacle.

It should be noted that theinner chamber is surrounded on all sides bythe heat nonconducting substance, and that the only place where theinner clnnnbcr has any inetallic connection with the outer air isthrough the neck of the receptacle and side wall ot the cover, but theseparts are so thin that very little, if any, heat or cold is lost yreason of them.

I have shown a filling tube 15' in the cover 15, that communicates withthe water coinpartment of the cover. This filling tube may be used infilling and emptying the water compartment, and a cork or plug 15"provided for scaling up the tube. .ltis obvious that either hot or coldwater, cracked iceor some other temperature niainmining "substance maybe poured into the eon'ipartment through the filling tube. and that the"same resultis. obtained as when the water compartment is used with thesubstance confincd within it and heated or cooled therein. Itis alsoevidentthat some other cold storage substance may be substituted forwater,

as for instance salt bri may be used, which may be given a very lowdegree of temperature without freezing them solid.

In the claims I have employed the term temperature maintaining,substance, by which I mean. any substance which may be cooled to a lowdegree of temperature. or heated up, to a high degree of temperature,for maintaining in the receptacle for a limited period of time, either alow or a high degree of temperature.

I am aware that-.various other alterations,

and modificirtiogishfithis derice' are possi ble without departing fromthe spirit of my invention, and l do'notdesire therefore to 5( limitmyself except as may be necessary by the prior state of the art.

I claim as new and desire to secure by Letters Patent:

1. A receptacle comprising inner and outer walls and an outwardlyflaring neck secured to the upper end of the inner wall, a flange onsaid neck adapted to engage the upper edge of the onterwall, and ataper-1 ing cover removablyseatedin said neck and having an outwardlyrojeeting flange adapted to rest uponthe tinge of the'neck, a horizontalpartition-lathe cover, a body of temperature maintaining substance inthe lower part of the cover, and a heat nonconducting substance in theupper part of the cover.

in a deviceof the class described, a wall inclosing-a chamber and havingan outwardly flaring neck formed with an outwardly turned flange uponits lower edge soldered to the wall.

In a device of the class described, the combination of a wall inclosinga chamber, an wuwardly flaring necl: having ah out- 7 wardly turnedflange upon its lower edge, and a downwardly converging cover adapted tobe seated in said neck with its lower edge projecting down below theflange on the neck.

et. A. receptacle comprising inner and outer walls and an outwardlyflaring neck, and a downwardly converging cover adapted to be seated insaid neck with its lower et ge projecting down below the flaring neck soto form an annular space between the side wallof the neck and thesurrounding wall.

In witness whereof I have executed the above application this 12th dayof June 1908, at Chicago, county 'olf Cook. and State of Illinois.
